==========================================================
Explanation:
"Use 3 for pi" is something I've never seen a teacher do before. Usually it's "use 3.14 for pi".
Anyway, the diameter of this cylinder is 2 inches, which cuts in half to 1 inch. This is the radius.
The height is 10 inches.

V = pi*r^2*h
V = 3*1^2*10
V = 30 cubic inches approximately
